Description

Large-diameter steel tower frame of split type fan

Technical Field

The utility model relates to a fan steel pylon.

Background

Generally, the fan tower frame of the tower cylinder and the ring forging integral flange, which is produced by rolling steel plates into a ring shape and then welding, is most commonly applied due to the characteristics of simple structure, small occupied area, convenience and quickness in factory construction and the like.

Because the wind generating set is continuously enlarged, in order to bear larger wind load, the requirement on a fan tower is higher and higher, the wall thickness of a steel plate is larger and larger, and a large-diameter tower barrel is produced at the same time, and the diameter of the tower barrel cannot be increased due to the limitation of transportation conditions such as height limit, line width and the like (the maximum limit of road transportation in China is 5m at present) of the tower barrel produced in a mode of rolling the steel plate into a ring shape and then welding.

Disclosure of Invention

In order to overcome the not enough of prior art, the utility model provides a big diameter's piece formula fan steel pylon solves the transportation problem of road limit for height line width that the tower section of thick bamboo of big diameter exists, reduces the cost of transportation.

The utility model provides a technical scheme that its technical problem adopted is:

a large-diameter steel tower frame for a split type fan comprises at least three tower cylinder bodies and ring-forged flange bodies, wherein longitudinal flanges are arranged on the side edges of the tower cylinder bodies, metal cushion blocks are clamped between the longitudinal flanges of adjacent tower cylinder bodies, and the two longitudinal flanges are fixedly connected through first bolts; the ring-forged flange plate bodies are arranged at the top end and the tail end of the tower cylinder plate body, and adjacent ring-forged flange plate bodies are connected through a flange connecting piece.

Furthermore, bolt holes are formed in two sides of the flange connecting piece, and second bolts penetrate through the bolt holes and are fixedly connected with the ring forging flange body on the two sides respectively.

Still further, the steel pylon of piece formula fan still includes bearing structure, bearing structure includes H shaped steel and H shaped steel connecting seat, sets up on each a section of thick bamboo lamellar body H shaped steel connecting seat, fixed connection between the H shaped steel connecting seat on the adjacent a section of thick bamboo lamellar body H shaped steel.

Furthermore, the first bolt joints between the longitudinal flanges and the second bolt joints between the ring-forged flange sheet body and the flange connecting piece are subjected to gluing treatment.

The utility model discloses, be a plurality of tower section of thick bamboo and flange lamellar body with the major diameter tower section of thick bamboo and flange split, after transporting the destination, the lamellar body passes through high strength bolted connection with the lamellar body and becomes complete pylon.

The beneficial effects of the utility model are that: 1. the transportation problem of road height limit and line width existing in a tower barrel with a large diameter is solved; 2. the tower drum produced by the annular welding mode formed by rolling the steel plates can be transported only one car and one drum, and the piece-separating tower drum can be stacked by one car and has a plurality of pieces (namely one car and a plurality of drums), so that the transportation cost is reduced; 3. the increase of the diameter of the tower drum can reduce the thickness of the steel plate of the tower drum, and solve the problems of difficult rolling of the steel plate with large thickness, complex process and the like; 4. and the integral reliability of the segmented tower is enhanced.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 5, the large-diameter steel tower for the split type fan comprises at least three tower cylinder sheets 1 and ring-forged flange sheets 2, wherein longitudinal flanges 3 are arranged on the side edges of the tower cylinder sheets 1, metal cushion blocks 4 are clamped between the longitudinal flanges 3 of the adjacent tower cylinder sheets 1, and the two longitudinal flanges 3 are fixedly connected through first bolts 5; the ring-forged flange plate bodies 2 are arranged at the top end and the tail end of the tower cylinder plate body 1, and adjacent ring-forged flange plate bodies 2 are connected through flange connecting pieces 6.

Further, bolt holes are formed in two sides of the flange connecting piece 6, and second bolts 7 penetrate through the bolt holes to be fixedly connected with the ring-forged flange pieces 2 on the two sides respectively.

Still further, the steel pylon of piece formula fan still includes bearing structure, bearing structure includes H shaped steel 8 and H shaped steel connecting seat 9, sets up on each piece of a tower section of thick bamboo lamellar body 1H shaped steel connecting seat 9, fixed connection between the H shaped steel connecting seat 9 on the adjacent tower section of thick bamboo lamellar body 1H shaped steel 8.

Furthermore, the joints of the first bolts 5 between the longitudinal flanges and the joints of the second bolts 7 between the ring-forged flange body and the flange connecting piece are subjected to gluing treatment.

The manufacturing process of the large-diameter steel tower frame of the split type fan in the embodiment is as follows:

step 1, coiling a steel plate into a ring shape, welding the ring shape, and then dividing the ring shape into a plurality of tower cylinder sheets 1, wherein 3 sheets are shown in figure 1;

step 2, the ring-forged flange is integrally ring-forged and formed and then is divided into ring-forged flange sheet bodies 2 with the same number as that of the tower barrels;
